Lehm Patent No. 95,728, dated October 12, 1869.'

The Schedule refe/ned to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, L. M. ROBY, of Leesville, in the county of Carroll, in the State of Ohio, have'invented a new and useful Improvement in Foot or Bed-Warmers; and that the following, taken'inconnection with the accompanying plate of drawings, hereinafter re ferred to, forms a full and exact specification of the same,'wherein I have set forth the nature and principles of my said improvement, by which my invention may be distinguished from others of a similar class, together withv such parts as I claim, and desire to secure by Letters Patent.-

My invention relates .to that class of devices which is used for the purpose of retaining heat for the purpose of imparting the same to the feet, 0r to the beds of invalids, and consists in a cloth -covered cylindrical chamber filled with some non-conducting substance,l

and enclosing a metallic heat-radiator, all in the manner and form hereinafter specified.

In the accompanying plate of drawings, which illustrates my invention, and forms a part of the specification thereoff Figure l isa longitudinal vertical section, showing the component parts of my invention, to wit, the heatradiator A, the non-conducting cylindrical chamber B, the cloth covering G, aud the stopper D.

Figure 2 is a horizontal section.

The heatradiator A is formed of any kind of metal which I prefer to make available, and is provided with the projection E, which may either be east solid with The object of these projections is to prevent the surface of the radiator from coming in contact with the inside of the non-conducting cylindrical chamber, and protecting the same from fusion, no matter to what de# gree the said radiator is heated.

The peripheral surface F, of the cylindrical chamber B, may be composed of any kindof metallic or earthen substances which I deem it expedient to use, and is lled with sand, coal, or some other non-conducting substance.

The cloth.l cap F, secured by a button at K, holds lthe plug Diirmly in 'its place.' I am aware that vaious devices have been hereto-- fore in use for the purpose of retaining heat, by means of a non-conducting envelope or wrapper. I do not claim broadly an implement for that purpose, irrespective of the arrangement of the parts of the same; but

I claim the arrangement herein described of the Y metallic heat-radiator A, with its projection E, and

the cloth-covered nou-conducting cylindrical chamber with its cap I, and plug D, when applied as herein set forth. L. M ROBY.
